The attached file contains a function that needs to have the first order derivative taken. I took the derivative, but I am making a mistake in the algebra simplification of the result. Would you please take a look.
I am working on a dynamic programming problem, and one part of it requires that I take the derivative of the function.
Below is the work that I did.
My study partner worked it out like this:
I think there is a sign mistake in my partner's work. He thinks there is a sign mistake in mine.
Would you work the problem and let me see where the mistake is?© BrainMass Inc. brainmass.com February 24, 2021, 2:22 pm ad1c9bdddf
There's a mistake in your partner's work:
From ... f '(x) = 4x + [ (2/5) * ...
The algebraic simplification problem for after u-substitution derivations are determined.
